ABSTRACT

A method for forming an embroidery pattern which comprises embroidering a cloth ( 1 ) for embroider by the use of an ordinary embroidery yam as a needle thread ( 2 ) and, as a bobbin thread ( 5 ), a yam obtained by twisting together an ordinary yarn used usually and a yam formed with a material capable of thermal fusion splicing or a yam obtained by covering an ordinary yam with a material capable of thermal fusion splicing, then heating them to fuse the material capable of thermal fusion splicing in the bobbin thread ( 5 ) and splice the ordinary yam of the bobbin thread and the needle thread ( 2 ) appearing on the back of the above cloth ( 1 ) to the back of the above cloth ( 1 ), and cutting each needle thread ( 2 ) appearing on the front surface of the cloth ( 1 ) at an intermediate portion thereof, thereby fluffing the needle thread ( 2 ) out; and a cloth having an embroidery pattern formed by the method or a method similar to that. The method can be used for obtaining an embroidery pattern which is stereoscopic and profound and forming an embroidery pattern of an intricate shape with ease.

TECHNICAL FIELD

The present invention relates to a cloth having an embroidery patternand a method for forming the embroidery pattern.

BACKGROUND ART

FIG. 6 shows how conventional sewing machine embroidery is performed. Aprocedure, wherein a needle thread 2 is passed through from the frontsurface to the back surface of a cloth 1, hooked to a bobbin thread 3 asshown in FIG. 6(B) and taken out to the front surface, is repeated. As aresult, embroidery of letters, symbols, figures, etc. (hereaftergenerally referred to as an embroidery pattern) is formed by the needlethread 2 on the front surface as shown in FIG. 6(A). However, theembroidery pattern formed in this way is flat and not stereoscopic.

In addition, when the cloth 1 having the conventional embroidery patternis used for clothing making direct contact with the skin, the bobbinthread 3 and the fold-back portion of the needle thread 2 entangled withthe bobbin thread 3 on the back surface of the cloth 1 make directcontact with the skin and irritates the skin, whereby an uncomfortablefeeling is given and may cause inflammation on the skin. To solve thisproblem, the cloth 1 having the embroidery pattern is cut off around thecontour of the embroidery pattern, and this cloth is bonded onto a cloth4 for clothing or the like as shown in FIG. 7. However, this methodtakes time and effort to cut off the cloth 1 around the contour of theembroidery pattern. Furthermore, the cutting becomes difficult unlessthe embroidery pattern has a simple and plain shape. Still further, theportion of the embroidery pattern becomes thick and stiff.

In consideration of these points, an object of the present invention isto provide a stereoscopic and profound embroidery pattern, and a secondobject of the present invention is to form an embroidery pattern withoutcutting off the cloth having the embroidery pattern even when theembroidery pattern has an intricate shape.

DISCLOSURE OF INVENTION

In order to attain the above-mentioned objects, a cloth having anembroidery pattern in accordance with the present invention ischaracterized in that the intermediate portion of each needle thread ofthe embroidery pattern, appearing on the front surface of a cloth, iscut and removed to fluff the needle threads.

An embroidery pattern having needle threads fluffed as described aboveis formed as described below for example. That is to say, an embroiderypattern is obtained by embroidering layers of an embroidery cloth andone or plural cloths or sheets overlaid on the embroidery cloth, by theuse of an ordinary embroidery yarn as a needle thread and, as a bobbinthread, a yarn obtained by twisting together an ordinary yarn usedusually (hereafter simply referred to as an “ordinary yarn”) as a bobbinthread for embroidery and a yarn formed of a material capable of thermalfusion splicing or a yarn obtained by covering an ordinary yarn with amaterial capable of thermal fusion splicing, by carrying out heating tofuse the material capable of thermal fusion splicing in the bobbinthread and to splice the ordinary yarn of the bobbin thread and theneedle thread appearing on the back surface of the cloth to the backsurface of the cloth, and by cutting and removing the intermediateportion of each needle thread appearing on the front surface, and byremoving the overlaid cloths or sheets to form an embroidery patternhaving fluffed needle threads on a desired cloth.

A bobbin thread formed of a material capable of thermal fusion splicingmay be used instead of the above-mentioned bobbin thread. In this case,the whole of the bobbin thread is fused, and the needle thread appearingon the back surface of the cloth is spliced to the back surface of thecloth.

Furthermore, an embroidery pattern having fluffy needle threads isformed on a desired cloth by embroidering an embroidery sheet, at leastthe back surface of which is treated so that no yarn adheres thereto andon which one or plural cloths or sheets are overlaid, by the use of anordinary embroidery yarn as a needle thread and, as a bobbin thread, ayarn obtained by twisting together an ordinary yarn and a yarn formed ofa material capable of thermal fusion splicing or a yarn obtained bycovering an ordinary yarn with a material capable of thermal fusionsplicing, by overlaying the embroidery sheet on a cloth on which anembroidery pattern is formed, with the front surface of the embroiderysheet placed upward, by carrying out heating to fuse the materialcapable of thermal fusion splicing in the bobbin thread and to splicethe ordinary yarn of the bobbin thread and the needle thread appearingon the back surface of the sheet to the cloth, by cutting and removingthe intermediate portion of each needle thread appearing on the frontsurface, and by separating the embroidery sheet and the cloths or sheetsoverlaid thereon from the cloth.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, embodiments of the present invention will be described.

In a first embodiment, a general and ordinary yarn for embroidery isused as a needle thread 2. Furthermore, a yarn obtained by twistingtogether an ordinary yarn and a yarn formed of a material capable ofthermal fusion splicing, which becomes an adhesive when fused by heat,so as to be configured to include the material capable of thermal fusionsplicing, or a yarn obtained by passing an ordinary yarn through theliquid of a fused material capable of thermal fusion splicing so thatits surface is covered with the material capable of thermal fusionsplicing so as to be configured to include the material capable ofthermal fusion splicing, is used as a bobbin thread 5. The materialcapable of thermal fusion splicing may be colorless or colored.

An embroidery pattern is formed on a cloth 1 by the use of the needlethread 2 and the bobbin thread 5 as shown in FIG. 1, and the formedembroidery pattern is heat-pressed with a heater, such as an iron, fromabove or from the back surface of the cloth 1 to fuse the materialcapable of thermal fusion splicing in the bobbin thread 5. Hence, thematerial capable of thermal fusion splicing becomes an adhesive, wherebythe ordinary yarn in the bobbin thread 5 and the portion of the needlethread 2 appearing on the back surface of the cloth 1 are spliced to theback surface of the cloth 1. The means for heat-pressing is not limitedto the iron, but any other appropriate means can be used.

Next, the intermediate portion of each needle thread 2 indicated by thebroken line of FIG. 1(A) is cut and removed. Hence, the needle threads 2are fluffed, and it is possible to obtain a stereoscopic and profoundembroidery pattern. Furthermore, even an embroidery pattern having anintricate shape can be formed easily without cutting the cloth 1 oroverlaying the cloth 1 on another cloth.

In a second embodiment, an ordinary yarn for embroidery is used as theneedle thread 2, just as in the case of the above-mentioned firstembodiment. However, a yarn formed of only a material capable of thermalfusion splicing, which becomes an adhesive when fused by heat, is usedas the bobbin thread 5. An embroidery pattern is formed on the cloth 1by the use of the needle thread 2 and the bobbin thread 5, just as inthe case of the first embodiment, and the formed embroidery pattern isheat-pressed with a heater, such as an iron, from above or from the backsurface of the cloth 1 to fuse the bobbin thread 5. Hence, the materialcapable of thermal fusion splicing, that is, the bobbin thread 5,becomes an adhesive, whereby the portion of the needle thread 2appearing on the back surface of the cloth 1 is spliced to the backsurface of the cloth 1 as shown in FIG. 2. Thus, in this case, thebobbin thread 5 does not remain in a clear form, unlike the case of thefirst embodiment wherein the bobbin thread 5 remains on the back surfaceof the cloth 1 as shown in FIG. 1(B).

Next, the intermediate portion of each needle thread 2 appearing on thefront surface is cut and removed, just as in the case of the firstembodiment. Hence, the needle threads 2 are fluffed, and it is possibleto obtain a stereoscopic and profound embroidery pattern.

The basic requirements of the first and second embodiments are describedabove. In reality, embroidery is carried out in a condition wherein oneor plural cloths or sheets are overlaid additionally on the cloth 1. Theadditionally overlaid cloths or sheets are removed after theintermediate portion of each needle thread 2 is cut and removed. Byoverlaying the cloths or sheets in this way, the intermediate portion ofeach needle thread 2 can be cut and removed easily. Furthermore, byappropriately selecting the whole thickness by adjusting the number ofthe cloths or sheets, the lengths of the needle threads 2 remainingafter the cutting can be adjusted to a desired equal dimension. Stillfurther, the overlaid cloths or sheets prevent the fused materialcapable of thermal fusion splicing in the bobbin thread 5 from flowingto the upper portions of the needle threads 2, whereby the needlethreads 2 are not spliced to the front surface of the cloth 1, therebynot becoming in a falling condition. Hence, all the needle threads 2remaining after the cutting stand upright and have an equal length,thereby being effective in obtaining a stereoscopic embroidery pattern.

In a third embodiment, an ordinary yarn for embroidery is used as theneedle thread 2, and a yarn obtained by twisting together an ordinaryyarn and a yarn formed of a material capable of thermal fusion splicingor a yarn obtained by covered its surface with a material capable ofthermal fusion splicing, so as to be configured to include the materialcapable of thermal fusion splicing is used as the bobbin thread 5, justas in the case of the first embodiment. An embroidery sheet 6 isembroidered first.

On this embroidery sheet 6, an embroidery pattern is formed temporarily,and the embroidery sheet 6 is configured so that no yarn adheres to atleast the back surface thereof. More specifically, the back surface ofthe sheet made of paper, cloth, plastic or the like for example iscovered with a mold release agent, such as a silicon resin orfluorocarbon resin, so that the fused material capable of thermal fusionsplicing does not adhere thereto. Or the sheet itself is formed of aplastic sheet or the like formed of a resin used for a mold releaseagent.

Next, as shown in FIG. 3, the embroidery sheet 6, with its front surfaceplaced upward, is overlaid on a cloth 4 on which an embroidery patternis to be formed, and the embroidery pattern is heat-pressed with aheater, such as an iron, from above or from the back surface of thecloth 4 to fuse the material capable of thermal fusion splicing in thebobbin thread 5, just as in the case of the above-mentioned embodiment,whereby the ordinary yarn of the bobbin thread 5 and the needle thread 2appearing on the back surface of the sheet 6 are spliced to the cloth 4.The cloth 4 is formed of a cloth that is not scorched or degraded whensubjected to the heating.

Next, when the intermediate portion of each needle thread 2 appearing onthe front surface is cut and removed (see FIG. 4), and when the sheet 6is lifted while the cloth 4 is held down, the cut needle threads 2 comeout of the perforations in the sheet 6, and the sheet 6 is separatedfrom the cloth 4, whereby the embroidery pattern transferred from thesheet 6 is formed on the cloth 4. No embroidery threads appear on theback surface of the cloth 4, just as in the case of FIG. 7. Theabove-mentioned cutting and removing of the needle threads 2 may becarried out before the embroidery sheet 6 is overlaid on the cloth 4.

In the embroidery pattern transferred to the cloth 4 as described in theabove procedure, the bobbin thread 5 is spliced to the cloth 4 whileholding the needle threads 2 as shown in FIG. 5; hence, the needlethreads 2 remaining after the cutting do not come out. Furthermore, theneedle threads 2 become fluffy, just as in the case of theabove-mentioned embodiment.

The basic requirements of the third embodiment are described above. Inreality, embroidery is carried out in a condition wherein one or pluralcloths or sheets are overlaid additionally on the embroidery sheet 6,just as in the case of the above-mentioned first and second embodiments.The additionally overlaid cloths or sheets are removed together with theembroidery sheet 6 after the intermediate portion of each needle thread2 is cut and removed. By overlaying the cloths or sheets in this way,the intermediate portion of each needle thread 2 can be cut and removedeasily, the lengths of the remaining needle threads 2 can be adjusted,and all the remaining needle threads 2 stand upright, just as in thecase of the first and second embodiments.

In addition, in this embodiment, after the embroidery sheet 6 isremoved, the ordinary yarn of the bobbin thread 5 as well as the needlethreads 2 appear on the front surface of the cloth 4, thereby forming anembroidery pattern. Hence, an embroidery pattern in two colors can beobtained by appropriately selecting the colors of the needle thread 2and the ordinary yarn of the bobbin thread 5. Or a colorful embroiderypattern can be formed by the use of a plurality of colors includingwhite at each portion of the embroidery pattern.

As described above, in accordance with the present invention, the needlethreads are fluffed, whereby it is possible to obtain a stereoscopic andprofound embroidery pattern. Furthermore, the bobbin thread and theneedle threads appearing on the back surface of the cloth are coveredwith the material capable of thermal fusion splicing and unexposeddirectly, or in the case of the third embodiment, no threads appear onthe back surface of the cloth. Therefore, the threads do not irritatethe skin, thereby giving no uncomfortable feeling and causing noinflammation on the skin. Hence, it is not necessary to cut off thecloth around the contour of the embroidery pattern and to bond the clothto another cloth, whereby it is possible to easily form an embroiderypattern having an intricate shape. Still further, a colorful embroiderypattern can be formed easily, and the portion of the embroidery patterndoes not become thick or stiff.
